The angels visiting Avraham are Guardian Angels, a familiar scene on the streets of New York City.

Part of the Haftarah (the prophetic reading that accompanies the Torah reading) is also represented by the vessels surrounding the tent: “Go, he said, “and borrow vessels outside, from all your neighbors, empty vessels, as many as you can.”” Melachim 4:1
